ERATORS will not need iinding that last year's ere winter caused many blems — not the least of ch was fuel waxing in the nse cold.
lthough the oil companies put anti-waxing additives the derv, this is not done 1 the last possible moment ause of the extra cost. i-waxing additives which )1es the operator to do the himself are marketed by Power (Products) Ltd of Brompton Road, London. epending on the concenon of the additive blend, average cost is about El 1 [000 gallons of fuel treated. Power claims that the use uch an additive has no ;t on filter change periods lel consumption. '
ie additive is put into the A. storage tanks where it is • important to ensure that mixed adequately with the . The best way to do this irding to Sta-Power is to :he tank right down so the additive can go into the bottom of an empty tank. When the dery is pumped in, this ensures correct mixing. The mixing is not satisfactory if, for example, the tank is filled up each time the level drops to quarter full. The actual size of the tank is immaterial.
In cold weather fuel waxing is not the only problem. Icing can occur due to condensation from the depot storage tank getting into the vehicle system and freezing. Sta-Power also markets a product which is claimed to eliminate this. It is a petroleum based alcohol used in a concentration of abou. one part in 4,500 which absorbs the moisture. It can also be used in conjunction with an anti-waxing additive.
Sta-Power claims that it is possible to cope with temperatures down to —22°C (-8°F) using these products although the company stresses that treating the fuel before the cold weather starts is essential.
